With a total investment of 500 million yuan, the Qiantang Leap project for the deep processing of reclaimed aluminum and copper has recently begun construction in Tianjin Ziya Circular Economy Industrial Zone. After the completion of the project, it will form an annual production capacity of 95,000 tons of aluminum, copper alloy ingots and deep processing products, ranking first in the same industry in the city.
It is reported that Tianjin Qiantang Feiyue Company is a resource regeneration and recycling enterprise established by Zhejiang Taiyue China Feiyue Group based on the Ziya Dental Park platform. The company's newly-built reprocessing project for reclaimed aluminum and copper is planned to cover an area of ​​330,000 square meters, with an initial investment of 280 million yuan. Advanced raw material cleaning, aluminum smelting, profile extrusion deep processing and copper smelting deep processing and supporting and auxiliary equipment will be introduced. The imported aluminum and copper raw materials will be cleaned, dismantled, smelted, cast, drawn, and refined. After the project is put into production, it can annually produce 50,000 tons of aluminum alloy ingots, 10,000 tons of aluminum deep-processed products such as aluminum extrusion profiles, radiators, and motor shells, 25,000 tons of copper pipe rods, copper profiles, and copper wire rods, and copper turbines. Raw materials, bearings, and copper alloy ingots are 10,000 tons, with an estimated annual sales income of 5 billion yuan.
Solar cells use sunlight to generate electricity. As long as the sun shines on the battery, it will continue to generate electricity. It is a clean energy with the advantages of safety, reliability, no noise and no consumption of raw materials. It has the advantages of great convenience for residents in remote areas. So what is the working principle of solar energy? Today we'll explore it. Solar cell is a device that directly converts light into electric energy through photochemical effect. When sunlight shines on the semiconductor pn junction, a new hole (electron pair) is formed. Under the action of the electric field, the hole flows from the N region to the p region, and the electron flows from the p region to the N region. After the circuit is connected, a current is formed to convert light energy into electric energy.Solar panel, also known as solar cell module, is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. It is an assembly composed of several solar cells assembled on a plate in a certain way. It is the core part of the solar power generation system.The earth, the green home for human survival.
With the development of human civilization, it has gradually become a victim of economic growth. Clean energy is imminent.
The sun concentrates 99.87 percent of the mass of the solar system, and one twenty-two percent of the energy radiates to the earth, becoming the main source of photosynthetic heat on the earth. Solar energy is one of the cleanest, most lasting and most magical energy of all.
